Parallel, Perpendicular, and Intersecting Lines
Parallel, Perpendicular, and Intersecting Lines: this Effortless Math guide explains the topic in plain language, shows how it works through solved examples, and gives you free practice to try immediately, so the idea sticks instead of staying abstract.
Kinds of Lines
- Horizontal Lines , Lines mapped from left-to-right or right-to-left and which are parallel to the (x)-axis in a plane are known as horizontal lines.
- Vertical Lines , Lines mapped from up to down or down to up and are parallel to the (y)-axis in a plane are known as vertical lines.
- Intersecting Lines, Whenever (2) lines cross one another and meet up at a point, they’re called intersecting lines. The point where they meet up is called the point of intersection.
Intersecting Lines Properties
- Intersecting lines link at a single point, and they can’t meet up at more than a single point.
- Intersecting lines meet up with one another at any angle that’s bigger than (0°) and lower than (180°).
- Perpendicular Lines, Whenever (2) lines intersect precisely at (90°), they’re called perpendicular lines.
- Parallel Lines, (2) lines are understood to be parallel if they don’t intersect at any point as well and they are equidistant.
Non-intersecting Lines Properties
- Non-intersecting lines don’t ever meet up, and they don’t share any kind of common point. They’re additionally called parallel lines.
- The gap in-between non-intersecting lines is constantly equal.
- The size of any common perpendicular drawn between the (2) non-intersecting lines is constantly equal.

Hints on Points and Lines
- Whenever (2) distinct points are linked, they create a line.
- A line goes in two directions forever.
- Parallel lines don’t intersect one another.
- The line that intersects at (90°) are called perpendicular lines.
- (2) or more points that lie on one straight line are called collinear points.
Parallel, Perpendicular, and Intersecting Lines, Example 1:
These two lines cross each other and intersect at (90°), so they are both intersecting and perpendicular to each other.
Parallel, Perpendicular, and Intersecting Lines, Example 2:
State whether the given pair of lines is parallel, perpendicular, or intersecting.
Solution:
These two lines do not intersect at any point so they are parallel.
